ABSTRACT
Aim: Venous air embolism is a rare but potentially life threatening complication of endoscopic retrograde cholangiopancreatography. Diagnosis is difficult because of the lack of specific signs or symptoms. Case: A 62-year-old man underwent endoscopic retrograde cholangiopancreatography for choledocholithiasis. A cardiovascular collapse occurred during the procedure. The echocardiography showed air within the right ventricle. Aspiration of air from the right ventricle was done and saved the patient's life. Conclusion: We highlight through this case that increased awareness is essential for prompt recognition of the air embolism to allow life-saving therapy.
Endoscopic treatment is the first-line treatment for biliary stones. It may be associated with various complications. We report the case of a 62-year-old patient who underwent endoscopic treatment for biliary stone. During the procedure, he experienced disturbed cardiac function due to the passage of air bubbles into the cardiac cavities. The bubbles were aspirated with a good outcome.
ABSTRACT
Thyroid storm is a life-threatening condition associated with multiorgan dysfunction and decompensation. We report the case of a 41-year-old woman having Graves' disease presented with thyroid storm complicated with liver dysfunction and portal hypertension in the absence of congestive heart failure or known liver disease. After successful therapeutic management, all biological, clinical and morphological abnormalities regressed.
Graves' disease is an immune system disorder that results in the overproduction of thyroid hormones. We report the case of a 41-year-old woman with Graves' disease who presented with reversible liver dysfunction and high blood pressure in the portal vein (located in the abdomen) following the withdrawal of her treatment.
ABSTRACT
INTRODUCTION: The impact of direct antiviral drugs (DAAs) on extrahepatic manifestations in chronic hepatitis C (CHC) has been poorly studied. AIM: To assess the prevalence of subclinical atherosclerosis in patients with CHC and the impact of DAAs on atherosclerotic lesions. Methods A 5-year prospective evaluative study, including patients followed for CHC at hepato-gastroenterology department. The subclinical atherosclerosis was assessed by ultrasound measurement of carotid intima-media thickness (IMTc) and the highest IMTc measurements from the left and right side defined the IMTc maximum (IMTc max). IMTc>75th percentile (IMTc75) define subclinical atherosclerosis with high cardiovascular risk. Patients were evaluated before (T0) and one year after DAAs therapy achievement (T1). RESULTS: At time T0, forty patients (median age: 55 y.; sex ratio M / F = 0.48), were included. Average value of IMTc max was 0.68 ± 0.16 mm. Subclinical atherosclerosis was noted in 82.5 %. At time T1, 28 patients were evaluated, all of whom completed sustained virological response (SVR). Compared to time T0, there was a significant increase in cholesterol (p = 0.001) and triglyceride (p = 0.009) levels. IMTc max was significantly higher at time T1 compared to T0 (0.75 Vs 0.67 mm, p = 0.04). Prevalence of IMTc75 was 82.1% at time T0 and 75% at time T1 (p=0.5). CONCLUSIONS: SVR, in CHC patients treated with DAA, was associated with worsening of carotid atherosclerotic lesions.

Aim: Ruptures of the intra-abdominal vein causing a spontaneous hemoperitoneum in cirrhotic patients is a rare condition. However, diagnosis must be considered early in cirrhotic patients with hematic ascites as a delayed diagnosis with hemodynamic instability is associated with a poor prognosis. Case report: We present the case of a 54-year-old cirrhotic patient who presented a spontaneous hemoperitoneum due to the rupture of the intra-abdominal vein that was diagnosed during exploratory laparoscopy. Conclusion: Early diagnosis and management of spontaneous hemoperitoneum due to the rupture of intra-abdominal vein helps improve its prognosis.
Spontaneous hemoperitoneum is a rare but catastrophic condition caused by the rupture of the liver, spleen or abdominal vessels. In patients with cirrhosis, diagnosis of spotaneous hemoperitoneum is difficult. This is a case report of a 54-year-old cirrhotic man with a spontaneous hemoperitoneum due to the rupture of a vein within the abdomen. The diagnosis was suspected as the patient had signs of blood in the abdomen. To confirm spontaneous hemoperitoneum, the doctors performed a procedure called exploratory laparoscopy, which involves inserting a small camera into the abdomen. The laparoscopy confirmed the presence of blood and thus the diagnosis of spontaneous hemoperitoneum.
ABSTRACT
Unlike liver and lung, the stomach is rarely a metastatic location for cancers. We report a case of a 62-year-old man known to have lung adenocarcinoma poorly differentiated presented with melena 1 month after diagnosis. Upper endoscopy revealed an ulcerated tumor in the prepyloric antrum. The diagnosis of gastric metastasis from pulmonary cancer was confirmed by the immunohistochemical staining for the thyroid transcriptional factor-1 and the pattern cytokeratine CK7+/CK20-. In conclusion, gastric metastasis from primary lung cancer is a rare phenomenon that every clinician must keep in mind.

ABSTRACT
Usually, fatty hepatic infiltration is diffuse and homogeneous. However, in some cases, it can be localized simulating benign or malignant tumors. We present a case of a 61-year-old female patient with family history of malignancy: sister with lung cancer, an other sister with colon cancer and a mother with breast cancer; who presented with multiple hepatic nodules at the ultrasonography images. CT scan and MRI were not sufficient to pose a certain diagnosis which was later confirmed by liver biopsy.

ABSTRACT
Various environmental factors affecting the human microbiota may lead to gut microbial imbalance and to the development of pathologies. Alterations of gut microbiota have been firmly implicated in digestive diseases such as hepatic encephalopathy, irritable bowel syndrome and diverticular disease. However, while these three conditions may all be related to dysfunction of the gut-liver-brain axis, the precise pathophysiology appears to differ somewhat for each. Herein, current knowledge on the pathophysiology of hepatic encephalopathy, irritable bowel syndrome, and diverticular disease are reviewed, with a special focus on the gut microbiota modulation associated with these disorders during therapy with rifaximin. In general, the evidence for the efficacy of rifaximin in hepatic encephalopathy appears to be well consolidated, although it is less supported for irritable bowel syndrome and diverticular disease. We reviewed current clinical practice for the management of these clinical conditions and underlined the desirability of more real-world studies to fully understand the potential of rifaximin in these clinical situations and obtain even more precise indications for the use of the drug.

INTRODUCTION: The ADRESS-HCC score allows predicting the risk of occurrence of Hepatocellular carcinoma in cirrhosis at one year of follow-up. AIM: Measuring the performance of ADRESS-HCC in predicting the risk of degeneration on post-viral cirrhosis, in a gastroenterology department in Tunisia. METHODS: Retrospective study, including patients followed for compensated viral cirrhosis in the gastroenterology department of the Mohamed Taher Maamouri hospital. The ADRESS-HCC score was calculated at diagnosis of cirrhosis. We divided patients into two groups depending on whether they developed Hepatocellular carcinoma or not. We evaluated the performance of the ADRESS-HCC score in predicting the risk of Hepatocellular carcinoma according to a threshold value. RESULTS: We enrolled 60 patients; the mean age was 62 years. Twenty-five patients developed hepatocellular carcinoma during follow-up. The mean value of ADRESS-HCC score was 5.08. To predict the occurrence of hepatocellular carcinoma at 1 year of follow-up, the area under the curve of the ADRESS-HCC score was 0.74 (p=0.01). For a threshold value of 5.63 its sensitivity was 91 % with a negative predictive value of 95.83%. CONCLUSION: The ADRESS-HCC score had an average performance in predicting degeneration in post-viral cirrhosis.

Introduction: severe acute liver injury (SALI) formerly known as severe acute hepatitis is an acute inflammation of the liver with markers of liver injury (elevated transaminases) and signs of hepatocellular failure (jaundice and INR greater than 1.5) according to the latest definition of the European Association for the Study of the Liver (EASL). An important prognostic factor in SALI is the development of hepatic encephalopathy (HE) and thus its progression to acute liver failure (ALF), formerly known as acute severe hepatitis. The purpose of this study is to investigate factors predicting the development of hepatic encephalopathy during SALI. Methods: we conducted a retrospective study of patients treated for SALI between January 2000 and December 2019. We divided patients into two groups depending on whether hepatic encephalopathy occurred. We performed an analytical study comparing the two groups according to their epidemiological, biological and evolutionary data. Results: data from the medical records of fifty-nine patients were collected. A virus was the most frequent cause (63%). Hepatic encephalopathy occurred in 15 patients (25.4%). Factors predicting the development of HE in univariate analysis were a delay in consultation of more than 9 days, an INR level of more than 2.45, a bilirubin level of more than 230 µmol/l, creatinine greater than 60.5 µmol/l, urea greater than 5.5 mmol/l and MELD score greater than 26.5 (p=0.023, p=0.017, p=0.0001, p=0.049, p=0.0001, p=0.0001 respectively). Autoimmune hepatitis and an undetermined cause were associated with the development of HE (p=0,003 and p=0,044, respectively). In multivariate analysis, autoimmune aetiology and a urea level above 5.5 mmol/l were significantly associated with the occurrence of HE. No statistically significant differences were found between the two groups with regard to age, sex and diabetes. Conclusion: SALI is a rare disease, mainly due to a virus in our country. Predictive factors of HE are important for early identification of patients at risk of adverse outcomes.

Osteopetrosis is a rare genetic bone disorder characterized by a defect in osteoclasts recruitment and function. Its manifestations are numerous and they mainly include skeletal and dental deformities, cranial nerve entrapment and infections. Over time, osteoclastic expansion invades bone marrow leaving little space for hematopoietic cells. As a result, extramedullary hematopoiesis takes place in the reticular system mainly in the spleen and liver. In these patients, portal hypertension can occur as a result of extramedullary hematopoiesis associated splenomegaly. We are reporting in this article a rare case of spontaneous bacterial peritonitis associated with portal hypertension in a patient with osteopetrosis.
ABSTRACT
The stomach is rarely a metastatic site of other primary cancers. Gastric metastasis from colonic cancer is exceptional. We hereby report a case of a 54-year-old male patient who underwent a right hemicolectomy for right-sided colon cancer. The pathology exam revealed well differentiated adenocarcinoma, it was classified stage IIb. Regular controls performed including colonoscopy were normal. Four years after colectomy, the patient was admitted for hematemesis with epigastric pain with detoriation of general condition . Gastroscopy revealed a large ulceroproliferative mass in the antropyloric region. Histology showed that this tumor was an adenocarcinoma similar to the primary right colon cancer, which led to the diagnosis of metastatic gastric cancer originating from colon cancer.
ABSTRACT
Hepatitis B virus (HBV) infection remains a serious public health concern worldwide despite the availability of an efficient vaccine and the major improvements in antiviral treatments. The aim of the present study is to analyze the mutational profile of the HBV whole genome in ETV non-responder chronic HBV patients, in order to investigate antiviral drug resistance, immune escape, and liver disease progression to Liver Cirrhosis (LC) or Hepatocellular Carcinoma (HCC). Blood samples were collected from five chronic hepatitis B patients. For each patient, two plasma samples were collected, before and during the treatment. Whole genome sequencing was performed using Sanger technology. Phylogenetic analysis comparing the studied sequences with reference ones was used for genotyping. The mutational profile was analyzed by comparison with the reference sequence M32138. Genotyping showed that the studied strains belong to subgenotypes D1, D7, and D8. The mutational analysis showed high genetic variability. In the RT region of the polymerase gene, 28 amino acid (aa) mutations were detected. The most significant mutations were the pattern rtL180M + rtS202G + rtM204V, which confer treatment resistance. In the S gene, 35 mutations were detected namely sP120T, sT126S, sG130R, sY134F, sS193L, sI195M, and sL216stop were previously described to lead to vaccine, immunotherapy, and/or diagnosis escape. In the C gene, 34 mutations were found. In particular, cG1764A, cC1766G/T, cT1768A, and cC1773T in the BCP; cG1896A and cG1899A in the precore region and cT12S, cE64D, cA80T, and cP130Q in the core region were associated with disease progression to LC and/or HCC. Other mutations were associated with viral replication increase including cT1753V, cG1764A/T, cC1766G/T, cT1768A, and cC1788G in the BCP as well as cG1896A and cG1899A in the precore region. In the X gene, 30 aa substitutions were detected, of which substitutions xT36D, xP46S, xA47T, xI88F, xA102V, xI127T, xK130M, xV131I, and xF132Y were previously described to lead to LC and/or HCC disease progression. In conclusion, our results show high genetic variability in the long-term treatment of chronic HBV patients causing several effects. This could contribute to guiding national efforts to optimize relevant HBV treatment management in order to achieve the global hepatitis elimination goal by 2030.
ABSTRACT
Neuroendocrine carcinoma (NEC) in the stomach represents a rare and rapidly growing type of gastric tumors. They are considered a distinct entity of neuroendocrine tumors characterized by an aggressive behavior and high metastases rate. On the other hand, spleen metastases of neuroendocrine tumors are extremely rare. We report the first case of spleen metastases of gastric neuroendocrine carcinoma. The patient was a 54-year-old male who presented with a 10-month history of epigastralgia. Upper gastro-intestinal endoscopy revealed a 5 cm ulcerative lesion located in the greater gastric curvature. Biopsies with immunohistochemical staining revealed gastric neuroendocrine carcinoma. Abdominal computed tomography showed thickening of the stomach with two large solid spleen lesions. Abdominal Magnetic Resonance Imaging and 18-fluorodexyglucose positron-emission tomography revealed peritoneal carcinosis and splenic metastases with splenic vein invasion. Clinicians should keep in mind that splenic metastases can arise from gastric neuroendocrine tumors (NETs).

Mucormycosis is a fungal infection affecting most commonly immunocompromised patients. Hereby, we report two cases: the first one is about a 61-year-old female with diabetes who presented with vomiting. The upper gastrointestinal endoscopy showed a budding grayish process which corresponded to an invasive mucormycosis in histology. As laboratory tests showed renal dysfunction, conventional amphotericin B was started at low doses since liposomal form was unavailable in Tunisia. Evolution was marked by a worsening of renal function leading to drug therapy withdrawal. Total gastrectomy was delayed because of a pulmonary embolism and was practiced 2 months later. The patient passed away 10 days after surgery. The second patient was a 59-year-old man who presented with vomiting and fast worsening of general state. At admission, he had a septic shock. Explorations revealed an invasive gastric mucormycosis. He died few days after admission. Thus, prompt diagnosis of mucormycosis and rapid initiation of treatment based on amphotericin B and surgical debridement is necessary to improve prognosis.
ABSTRACT
Background: Small bowel volvulus (SBV) is an aberrant rotation of the small bowel segment along the axis of its mesentery.Secondary SBV is the most frequent situation. Postoperative adhesions represent the main cause. On the other hand, primary SBV is an extremely rare situation. There are no predisposing anatomical abnormalities.Herein, we present a case of a 73-year-old-patient, with no surgical history, presenting primary SBV. Case presentation: A 73-year-old-patient presented to the emergency department with a one-day history of acute abdominal pain and vomiting. He had no medical comorbidities and no previous abdominal surgery.On examination, he was agitated and afebrile.Urgent computed tomography (CT) scan showed dilated small bowel loops with a "whirl sign".A laparotomy was performed. It revealed a 320° SBV of the distal jejunum and the proximal ileum. The small bowel was ischemic. There were no congenital malformations, no adhesions, and no internal hernia.We performed a detorsion of the small bowel. It regained good vitality. To avoid recurrence, we performed enteropexy of the terminal ileum, and the caecum to widen the mesenteric base.We noted no recurrence of the pathology after three months of follow-up. Conclusion: Primary SBV is an extremely rare situation. Physiopathology is still misunderstood. The clinical presentation is not specific. Diagnosis can be evoked by CT scan but can only be confirmed intraoperatively. The surgical treatment should be performed timely. Different techniques have been described to avoid recurrence. None of those techniques is consensual.
ABSTRACT
Several syndromic forms of digestive cancers are known to predispose to early-onset gastric tumors such as Hereditary Diffuse Gastric Cancer (HDGC) and Lynch Syndrome (LS). LSII is an extracolonic cancer syndrome characterized by a tumor spectrum including gastric cancer (GC). In the current work, our main aim was to identify the mutational spectrum underlying the genetic predisposition to diffuse gastric tumors occurring in a Tunisian family suspected of both HDGC and LS II syndromes. We selected the index case "JI-021", which was a woman diagnosed with a Diffuse Gastric Carcinoma and fulfilling the international guidelines for both HDGC and LSII syndromes. For DNA repair, a custom panel targeting 87 candidate genes recovering the four DNA repair pathways was used. Structural bioinformatics analysis was conducted to predict the effect of the revealed variants on the functional properties of the proteins. DNA repair genes panel screening identified two variants: a rare MSH2 c.728G>A classified as a variant with uncertain significance (VUS) and a novel FANCD2 variant c.1879G>T. The structural prediction model of the MSH2 variant and electrostatic potential calculation showed for the first time that MSH2 c.728G>A is likely pathogenic and is involved in the MSH2-MLH1 complex stability. It appears to affect the MSH2-MLH1 complex as well as DNA-complex stability. The c.1879G>T FANCD2 variant was predicted to destabilize the protein structure. Our results showed that the MSH2 p.R243Q variant is likely pathogenic and is involved in the MSH2-MLH1 complex stability, and molecular modeling analysis highlights a putative impact on the binding with MLH1 by disrupting the electrostatic potential, suggesting the revision of its status from VUS to likely pathogenic. This variant seems to be a shared variant in the Mediterranean region. These findings emphasize the importance of testing DNA repair genes for patients diagnosed with diffuse GC with suspicion of LSII and colorectal cancer allowing better clinical surveillance for more personalized medicine.

Leeches are carnivorous, hermaphroditic, segmented worms mainly found in fresh water. The majority of leech attachments are external and short-lasting. Internal surfaces can be involved. Yet, esophageal attachment is very rare. We report a case of a 59-year-old female who presented with hematemesis, melena and chest pain. Upper gastrointestinal endoscopy revealed a round black foreign body in the mid-third of the esophagus identified as a leech. We carefully extracted the worm with a forceps applied to the middle of its body. The diagnosis of leech infestation should be kept in mind when exploring gastrointestinal bleeding in patients living in rural areas and those with poor living conditions.
ABSTRACT
Treatment of diffuse large B-cell lymphoma (DLBCL) is based on immunochemotherapy with overall good outcomes. Complications related to the treatment or the disease itself can occur during follow-up. We herein report a case of a 37-year-old male who was diagnosed with stage IV gastric DLBCL. Subsequently, he underwent R-CHOP (rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone) chemotherapy. After six cycles of treatment, complete remission has been achieved. But afterwards, the patient presented with a symptomatic gastric obstruction related to a tight stenosis in the antro-fundic junction. Endoscopic dilation was performed and multiple macrobiopsies within the stenosis were taken. Pathological examination concluded to the fibrous character of the stricture. In cases of post-chemotherapy obstruction in gastric DLBCL, endoscopic treatment should be attempted carefully in patients with no evidence of active lymphoma. Diagnosis of fibrosis can avoid surgery and its morbidity.
ABSTRACT
Esophageal tuberculosis is a rare cause of infectious esophagitis, even in countries with endemic tuberculosis. This impairment is often secondary. We report a case of secondary esophageal tuberculosis in an immunocompetent patient, clinically revealed by dysphagia. Esophagogastroduodenoscopy showed a large ulcer in the middle third of the esophagus with a fistula opening in the center of the ulcer. Histopathological examination of multiple esophageal tissue biopsies revealed epithelioid cell granulomas without caseous necrosis. We completed with Computed Tomography (CT) scan of the chest which revealed a fistula of the middle third of the esophagus, multiple mediastinal necrotic adenopathies and diffuse pulmonary micronodules suggesting miliary tuberculosis. Sputum examination for acid-fast-bacilli was positive. Anti-tuberculosis treatment resulted in a good response with complete remission. It is therefore important to recognize and include this entity in the differential diagnosis of patients with dysphagia particularly in countries with a high incidence of tuberculosis.

Jejunal diverticulitis is an uncommon and underdiagnosed condition. Due to the rarity of This disease, diagnosis is often difficult and delayed. Medical treatment is usually sufficient for jejunal diverticulitis without peritonitis. Surgery is required in case of generalized peritonitis or voluminous abscess complicating diverticulitis. We report the case of a 76-year-old woman who suffered from recent abdominal pain. Diagnosis of uncomplicated jejunal diverticulitis was based on computed tomography (CT) scan. The evolution was favorable after antibiotic treatment. Jejunal diverticulitis have to be evoked among the differential diagnosis of patients with abdominal pain especially in the elderly and it is important for clinicians and radiologists to have awareness about this disease.
